      WOW: Women on the Water Sailing Registration Form
  • Junior Activities
    • Junior Keelboat Sailing is a Sailing School course that is open to teens who are either new to sailing, or want to expand their sailing skills to a larger boat. Students will learn basic boat-handling, sail trim, and seamanship skills in the Sonars. The class focuses on skippers and crew members working together to sail the boat on its proper course. By the end of the course, the students will be self-sufficient at day sailing in a keelboat. Learn more.

  • Keelboat Certification
    • The Chicago Yacht Club is a US Sailing Accredited Keelboat School and offers Basic Keelboat Certification courses as well as intermediate and private lessons. Our instructors are all certified professionals teaching on the best equipment in the city. Courses cover sailing theory, boat handling skills, safety and emergency techniques, anchoring and docking, heavy weather sailing, and navigation. No prior sailing experience needed! Learn more.

  • Match Racing
    • Match racing is a fun, fast growing form of the sport with more action per minute than your average day of racing. Whether you are a one design or big boat racer, team racing is a great way to improve your skills, including starting, tactics, boat handling, and understanding rules. There are opportunities for members of all levels to crew and skipper.

      At each meeting, we plan to head out on the water to run practice drills and races. After racing, all sailors are invited to Belmont to enjoy refreshments while we debrief with lessons from the day. See the schedule and learn more.

  • Sonar Rentals
    • CYC members may rent the Sonars for $80/hour or a $450 annual pass whenever the boats are not being used for teaching or racing. All skippers must complete a Sonar orientation before their first rental. The orientation fee is $80, and members receive a two-hour rental credit upon successful completion. Learn more

Sonar Fleet Membership Form


Please review the rules and complete the form below to apply for Sonar Fleet Membership.

The Sonar’s are durable, safe and fun. They appeal to all ages and skill levels, easily sailed by two people, but with a cockpit large enough for four people to enjoy. Responsive, but stable at 2000 lbs with a fixed lead keel and self bailing cockpit, it is easily driven with a mainsail, 100% jib, and spinnaker. Since its introduction in 80’s, the Sonar has blossomed into an International class.

Still, the Sonar, while not large or overly complicated, is a small keel boat that can overwhelm a completely novice sailor. We want to make sure you have the necessary basic skills to safely operate the boat before you set out to sea!

Complete the information on this form and you will be contacted by the Keelboat Director or a fleet member to discuss the necessary skills and arrange a time to meet and take a test sail. Required skills include tying a few simple knots while rigging the boat, demonstrating some basic sailing skills (tacking/gybing and stopping the boat) and boat maneuvers including leaving and returning to the dock.

The annual membership fee for the Sonar fleet is $450 and supports the operation and upkeep of the boats. Anyone can join the Sonar fleet with the payment of the membership fee, even if you haven’t taken the test sail yet.

As a member, your CYC membership account will serve as a ‘damage deposit’. In the event there is damage that needs repair, you may be liable for up to $2500. Coverage for the boats beyond that is under the club’s umbrella insurance policy.

Upon passing the skills check and test sail, you will be listed as a ‘qualified’ member and are free to reserve the boats, as available, for the entire calendar year. There is a reservation window that allows for reservations up to 30 days ahead. We also ask you give us 48 hours minimum notice, especially for weekend reservations, to coordinate launching and leave the dock with no more than five (5) souls aboard.
